• How to unmangle exported symbols from C++ in dynamic libraries in XCode on OSX

  - by Gerald

  I've been trying to develop a dynamic library in C++ that can be run-time loaded in an application. I finally got it working, but it's a little ugly. I have a function that takes a pointer to a C++ class as an argument, which looks like this: bool registerGrindPlugin( Grind::PluginManager* mgr ); But of course it's being exported as: _Z19registerGrindPluginPN5Grind13PluginManagerE I tried a .c file with a simple function and it exported fine as "registerGrindPlugin", but of course I can't pass a C++ class as the argument that way. Soo... my question is, is there a way to unmangle or alias the exported symbol so that I don't have to use a monstrosity like Z19registerGrindPluginPN5Grind13PluginManagerE in my dlsym call? I did see something about -alias_list as a linker option, but I haven't quite figured out how to use it in XCode. If that is the solution, can somebody provide some more details on how to use this?

• iPhone SDK:How do you play video inside a view? Rather than fullscreen.

  - by Jessica

  Hi, I am trying to play video inside a UIView, so my first step was to add a class for that view and start playing a movie in it using this code: - (IBAction)movie:(id)sender{ NSBundle *bundle = [NSBundle mainBundle]; NSString *moviePath = [bundle pathForResource:@"Movie" ofType:@"m4v"]; NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; theMovie.scalingMode = MPMovieScalingModeAspectFill; [theMovie play]; } But this just crashes the app when using this method inside it's own class, but is fine elsewhere. Does anyone know how to play video inside a view? and avoid it being full screen?

• Animating inline elements with JQuery

  - by rnielsen

  I am trying to show and hide an inline element (eg a span) using jquery. If I just use toggle(), it works as expected but if I use toggle("slow") to give it an animation, it turns the span into a block element and therefore inserts breaks. Is animation possible with inline elements? I would prefer a smooth sliding if possible, rather than a fade in. Thanks. <script type="text/javascript"> $(function(){ $('.toggle').click(function() { $('.hide').toggle("slow") }); }); </script> <p>Hello <span class="hide">there</span> jquery</p> <button class="toggle">Toggle</button>

• How to do simple math in datagridview

  - by EB

  I am new to C#. I have a datagridview with 9 columns. I am simply trying take the value in column 5 and subtract it from column 6. Then display the result in column 9. It seems simple enough.I know it's done in excel all the time. But I just cannot figure this out. Do I need to create a new class with a method called calculate columns? or does the datagridview class have something already built in that can handle this? Again, I am new to C#. Any help would be appreciated. Thank you, Oceantrain.

• How to let users edit list<T> content?

  - by iTayb

  I'm making an aspx page that can edit books. A book is an complex class with lots of properties. I've made an edit page for most of them, however I'm having trouble with showing edit options for my Sellers Proprety. It is an list<Seller> object. Seller is as follows: public class Seller { private string sellerName; private double price; } How can I print a list to the screen, and let the clinet edit it, then load it back to the object? Thank you very much.

• On Redirect - Failed to generate a user instance of SQL Server...

  - by Craig Russell

  Hello (this is a long post sorry), I am writing a application in ASP.NET MVC 2 and I have reached a point where I am receiving this error when I connect remotely to my Server. Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. I thought I had worked around this problem locally, as I was getting this error in debug when site was redirected to a baseUrl if a subdomain was invalid using this code: protected override void Initialize(RequestContext requestContext) { string[] host = requestContext.HttpContext.Request.Headers["Host"].Split(':'); _siteProvider.Initialise(host, LiveMeet.Properties.Settings.Default["baseUrl"].ToString()); base.Initialize(requestContext); } protected override void OnActionExecuting(ActionExecutingContext filterContext) { if (Site == null) { string[] host = filterContext.HttpContext.Request.Headers["Host"].Split(':'); string newUrl; if (host.Length == 2) newUrl = "http://sample.local:" + host[1]; else newUrl = "http://sample.local"; Response.Redirect(newUrl, true); } ViewData["Site"] = Site; base.OnActionExecuting(filterContext); } public Site Site { get { return _siteProvider.GetCurrentSite(); } } The Site object is returned from a Provider named siteProvider, this does two checks, once against a database containing a list of all available subdomains, then if that fails to find a valid subdomain, or valid domain name, searches a memory cache of reserved domains, if that doesn't hit then returns a baseUrl where all invalid domains are redirected. locally this worked when I added the true to Response.Redirect, assuming a halting of the current execution and restarting the execution on the browser redirect. What I have found in the stack trace is that the error is thrown on the second attempt to access the database. #region ISiteProvider Members public void Initialise(string[] host, string basehost) { if (host[0].Contains(basehost)) host = host[0].Split('.'); Site getSite = GetSites().WithDomain(host[0]); if (getSite == null) { sites.TryGetValue(host[0], out getSite); } _site = getSite; } public Site GetCurrentSite() { return _site; } public IQueryable<Site> GetSites() { return from p in _repository.groupDomains select new Site { Host = p.domainName, GroupGuid = (Guid)p.groupGuid, IsSubDomain = p.isSubdomain }; } #endregion The Linq query ^^^ is hit first, with a filter of WithDomain, the error isn't thrown till the WithDomain filter is attempted. In summary: The error is hit after the page is redirected, so the first iteration is executing as expected (so permissions on the database are correct, user profiles etc) shortly after the redirect when it filters the database query for the possible domain/subdomain of current redirected page, it errors out.

• How do you use Java 1.6 Annotation Processing to perform compile time weaving?

  - by Steve

  I have created an annotation, applied it to a DTO and written a Java 1.6 style annotationProcessor. I can see how to have the annotationProcessor write a new source file, which isn't what I want to do, I cannot see or find out how to have it modify the existing class (ideally just modify the byte code). The modification is actually fairly trivial, all I want the processor to do is to insert a new getter and setter where the name comes from the value of the annotation being processed. My annotation processor looks like this; @SupportedSourceVersion(SourceVersion.RELEASE_6) @SupportedAnnotationTypes({ "com.kn.salog.annotation.AggregateField" }) public class SalogDTOAnnotationProcessor extends AbstractProcessor { @Override public boolean process(final Set<? extends TypeElement> annotations, final RoundEnvironment roundEnv) { //do some stuff } }

• Concatenating databases with Squeryl

  - by Pengin

  I'm trying to use Squeryl to take the contents of a table from one database, and append it to the equivalent table in another database. The primary key will have to be reassigned in the process, but I'm getting the error NULL not allowed for column "SIMID". Why is this? object Concatenator { def main(args: Array[String]) { Class.forName("org.h2.Driver"); val seshA = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsA", "sa", "password"), new H2Adapter ) val seshB = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsB", "sa", "password"), new H2Adapter ) using(seshA){ import Library._ from(sims){s => select(s)}.foreach{item => using(seshB){ sims.insert(item); } } } } case class Simulation( @Column("SIMID") var id: Long, val date: Date ) extends KeyedEntity[Long] object Library extends Schema { val sims = table[Simulation] on(sims)(s => declare( s.id is(unique, indexed, autoIncremented) )) } }

• User Control as container at design time

  - by Luca

  I'm designing a simple expander control. I've derived from UserControl, drawn inner controls, built, run; all ok. Since an inner Control is a Panel, I'd like to use it as container at design time. Indeed I've used the attributes: [Designer(typeof(ExpanderControlDesigner))] [Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", typeof(IDesigner))] Great I say. But it isn't... The result is that I can use it as container at design time but: The added controls go back the inner controls already embedded in the user control Even if I push to top a control added at design time, at runtime it is back again on controls embedded to the user control I cannot restrict the container area at design time into a Panel area What am I missing? Here is the code for completeness... why this snippet of code is not working? [Designer(typeof(ExpanderControlDesigner))] [Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", typeof(IDesigner))] public partial class ExpanderControl : UserControl { public ExpanderControl() { InitializeComponent(); .... [System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust")] internal class ExpanderControlDesigner : ControlDesigner { private ExpanderControl MyControl; public override void Initialize(IComponent component) { base.Initialize(component); MyControl = (ExpanderControl)component; // Hook up events ISelectionService s = (ISelectionService)GetService(typeof(ISelectionService)); IComponentChangeService c = (IComponentChangeService)GetService(typeof(IComponentChangeService)); s.SelectionChanged += new EventHandler(OnSelectionChanged); c.ComponentRemoving += new ComponentEventHandler(OnComponentRemoving); } private void OnSelectionChanged(object sender, System.EventArgs e) { } private void OnComponentRemoving(object sender, ComponentEventArgs e) { } protected override void Dispose(bool disposing) { ISelectionService s = (ISelectionService)GetService(typeof(ISelectionService)); IComponentChangeService c = (IComponentChangeService)GetService(typeof(IComponentChangeService)); // Unhook events s.SelectionChanged -= new EventHandler(OnSelectionChanged); c.ComponentRemoving -= new ComponentEventHandler(OnComponentRemoving); base.Dispose(disposing); } public override System.ComponentModel.Design.DesignerVerbCollection Verbs { get { DesignerVerbCollection v = new DesignerVerbCollection(); v.Add(new DesignerVerb("&asd", new EventHandler(null))); return v; } } } I've found many resources (Interaction, designed, limited area), but nothing was usefull for being operative... Actually there is a trick, since System.Windows.Forms classes can be designed (as usual) and have a correct behavior at runtime (TabControl, for example).

• C++ Virtual Constructor, without clone()

  - by Julien L.

  I want to perform "deep copies" of an STL container of pointers to polymorphic classes. I know about the Prototype design pattern, implemented by means of the Virtual Ctor Idiom, as explained in the C++ FAQ Lite, Item 20.8. It is simple and straightforward: struct ABC // Abstract Base Class { virtual ~ABC() {} virtual ABC * clone() = 0; }; struct D1 : public ABC { virtual D1 * clone() { return new D1( *this ); } // Covariant Return Type }; A deep copy is then: for( i = 0; i < oldVector.size(); ++i ) newVector.push_back( oldVector[i]->clone() ); Drawbacks As Andrei Alexandrescu states it: The clone() implementation must follow the same pattern in all derived classes; in spite of its repetitive structure, there is no reasonable way to automate defining the clone() member function (beyond macros, that is). Moreover, clients of ABC can possibly do something bad. (I mean, nothing prevents clients to do something bad, so, it will happen.) Better design? My question is: is there another way to make an abstract base class clonable without requiring derived classes to write clone-related code? (Helper class? Templates?) Following is my context. Hopefully, it will help understanding my question. I am designing a class hierarchy to perform operations on a class Image: struct ImgOp { virtual ~ImgOp() {} bool run( Image & ) = 0; }; Image operations are user-defined: clients of the class hierarchy will implement their own classes derived from ImgOp: struct CheckImageSize : public ImgOp { std::size_t w, h; bool run( Image &i ) { return w==i.width() && h==i.height(); } }; struct CheckImageResolution; struct RotateImage; ... Multiple operations can be performed sequentially on an image: bool do_operations( std::vector< ImgOp* > v, Image &i ) { std::for_each( v.begin(), v.end(), /* bind2nd(mem_fun(&ImgOp::run), i ...) don't remember syntax */ ); } int main( ... ) { std::vector< ImgOp* > v; v.push_back( new CheckImageSize ); v.push_back( new CheckImageResolution ); v.push_back( new RotateImage ); Image i; do_operations( v, i ); } If there are multiple images, the set can be split and shared over several threads. To ensure "thread-safety", each thread must have its own copy of all operation objects contained in v -- v becomes a prototype to be deep copied in each thread.

• Generics and Exposing .Net Types For COM Consumers?

  - by IbrarMumtaz

  I remember seeing a question on my official MS 70-536 exam that talked about a simple class that was designed to be exposed for COM calling clients and etc. of all the members defined in the classes I chose the answer D. The one that used a generic. My question to you guys is this: If you were designing a .net custom type that was to be eventually consumed by a com caller or a com type .... of all the guidelines I have read on this subject. Generics is the one .Net topic I would not include in a class for this purpose I would omit such a data member or use something else? Am I right in thinking this. As soon as I saw this question I knew it was generics but I can't seem to prove it. Surely I did not make this up ... generics is a .net feature right?

• Does std::multiset guarntee insertion order?

  - by Naveen

  I have a std::multiset which stores elements of class A. I have provided my own implementation of operator< for this class. My question is if I insert two equivalent objects into this multiset is their order guaranteed? For example, first I insert a object a1 into the set and then I insert an equivalent object a2 into this set. Can I expect the a1 to come before a2 when I iterate through the set? If no, is there any way to achieve this using multiset?

• user defined Copy ctor, and copy-ctors further down the chain - compiler bug ? programmers brainbug

  - by J.Colmsee

  Hi. i have a little problem, and I am not sure if it's a compiler bug, or stupidity on my side. I have this struct : struct BulletFXData { int time_next_fx_counter; int next_fx_steps; Particle particles[2];//this is the interesting one ParticleManager::ParticleId particle_id[2]; }; The member "Particle particles[2]" has a self-made kind of smart-ptr in it (resource-counted texture-class). this smart-pointer has a default constructor, that initializes to the ptr to 0 (but that is not important) I also have another struct, containing the BulletFXData struct : struct BulletFX { BulletFXData data; BulletFXRenderFunPtr render_fun_ptr; BulletFXUpdateFunPtr update_fun_ptr; BulletFXExplosionFunPtr explode_fun_ptr; BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr; BulletFX( BulletFXData data, BulletFXRenderFunPtr render_fun_ptr, BulletFXUpdateFunPtr update_fun_ptr, BulletFXExplosionFunPtr explode_fun_ptr, BulletFXLifetimeOverFunPtr lifetime_over_fun_ptr) :data(data), render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } /* //USER DEFINED copy-ctor. if it's defined things go crazy BulletFX(const BulletFX& rhs) :data(data),//this line of code seems to do a plain memory-copy without calling the right ctors render_fun_ptr(render_fun_ptr), update_fun_ptr(update_fun_ptr), explode_fun_ptr(explode_fun_ptr), lifetime_over_fun_ptr(lifetime_over_fun_ptr) { } */ }; If i use the user-defined copy-ctor my smart-pointer class goes crazy, and it seems that calling the CopyCtor / assignment operator aren't called as they should. So - does this all make sense ? it seems as if my own copy-ctor of struct BulletFX should do exactly what the compiler-generated would, but it seems to forget to call the right constructors down the chain. compiler bug ? me being stupid ? Sorry about the big code, some small example could have illustrated too. but often you guys ask for the real code, so well - here it is :D EDIT : more info : typedef ParticleId unsigned int; Particle has no user defined copyctor, but has a member of type : Particle { .... Resource<Texture> tex_res; ... } Resource is a smart-pointer class, and has all ctor's defined (also asignment operator) and it seems that Resource is copied bitwise. EDIT : henrik solved it... data(data) is stupid of course ! it should of course be rhs.data !!! sorry for huge amount of code, with a very little bug in it !!! (Guess you shouldn't code at 1 in the morning :D )

• Nhibernate: mapping two different properties between the same 2 entities

  - by Carlos Decas

  I have a Class A: public class ClassA { public int ID {get; private set;} public string Code {get; private set;} public ClassB B {get; private set;} public IList<ClassB> ListB {get; private set;} } And a ClassB: public class ClassB { public int ID {get; private set;} public string Code {get; private set;} public ClassA A {get; private set;} //some other attributes... } And the Mappings: public ClassAMap() { Table("ClassA"); Id(classA => classA .ID, "ID").GeneratedBy.Identity(); Map(classA => classA.Code, "Code").Unique().Not.Nullable(); //HERE IS THE PROBLEM: -------- References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); //----- HasMany(classA => classA.ListB).Table("ClassB").KeyColumn("IDClassA").AsBag().Not.LazyLoad().Inverse().Cascade.AllDeleteOrphan(); } ClassB Mappings: public ClassBMap() { Table("ClassB"); Id(classB => classB.ID).GeneratedBy.Identity(); References(classB => classB.A, "IDClassA").ForeignKey("ID").Cascade.SaveUpdate(); } The mappings for ListB in classA worked ok, because at first the was only ListB property and not B, when i had to map B i tried this: References(classA => classA.B,"IDClassB"); The mapping test failed because B wasn't saved, so i did this: References(classA => classA.B,"IDClassB").Cascade.SaveUpdate(); This time B was saved, but by saving B, classA was inserted two times, by A.B and by B.A. How can i solve this problem? Why does it work for the ListB property and not for the B property? Thanks

  Hello all, I wish to create a "subtree" from an hclust object. For example, let's say I have the following object: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2, -5,-6, 3,4), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3,4,4.5) # define merge heights a$order <- 1:6 # order of leaves(trivial if hand-entered) a$labels <- 1:6# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result Now I wish the extract from it the following subtree: a <- list() # initialize empty object a$merge <- matrix(c(-1, -2, -3, -4, 1, 2 ), nc=2, byrow=TRUE ) a$height <- c(1, 1.5, 3) # define merge heights a$order <- 1:4 # order of leaves(trivial if hand-entered) a$labels <- 1:4# LETTERS[1:4] # labels of leaves class(a) <- "hclust" # make it an hclust object plot(a) # look at the result How could I access it?

• How does multiple implementing multiple COM interfaces work in C++?

  - by Martin

  I am trying to understand this example code regarding Browser Helper Objects. Inside, the author implements a single class which exposes multiple interfaces (IObjectWithSite, IDispatch). His QueryInterface function performs the following: if(riid == IID_IUnknown) *ppv = static_cast<BHO*>(this); else if(riid == IID_IObjectWithSite) *ppv = static_cast<IObjectWithSite*>(this); else if (riid == IID_IDispatch) *ppv = static_cast<IDispatch*>(this); I have learned that from a C perspective, interface pointers are just pointers to VTables. So I take it to mean that C++ is capable of returning the VTable of any implemented interface using static_cast. Does this mean that a class constructed in this way has a bunch of VTables in memory (IObjectWithSite, IDispatch, etc)? What does C++ do with the name collisions on the different interfaces (they each have a QueryInterface, AddRef and Release function), can I implement different methods for each of these?

• Documenting logic in javadoc

  - by smayers81

  I have a question about where to document logic in javadocs. For example, I have the following method signature in an interface: public int getTotalAssociationsAsParent(Long id, Long type); The method returns associations where the given ID is the parent and the association is of type 'type'. ID is required, but if type passed in is NULL, then I will return ALL associations where the ID is the parent. My question is where should this type of logic be documented? I hesitate putting it in the javadoc of the interface because that sort of constrains all implementing classes to adhere to that logic. Maybe in the future, I'll have an Impl class that throws an IllegalArgumentException if type is NULL. However, if I put it in non-javadoc in the Impl class, then consumers of this method won't know how the method behaves with a NULL type.

• java.lang.UnsupportedClassVersionError in eclipse

  - by Derek

  Hi all, I am not a Java programmer really, so I am posting this question. The exception is being thrown java.lang.UnsupportedClassVersionError in my main class in an eclipse project. If I comment out the imports that this class has, it compiles and runs fine. If I put the imports back in, it does not work. Does this mean that the libraries I am importing were compiled with a newer or older version of java than I have? when i do java -version on the system i get 1.5_07 I could've sworn this was actually working last week, but maybe some setting in eclipse got tweaked? Is the Java Build Path in eclipse what I need to look for to check the JRE and compiler versions?

• Using Constants in Perl

  - by David W.

  I am trying to define constants in Perl using the use Constant pragma: use Constant { FOO => "bar", BAR => "foo" }; I'm running into a bit of trouble, and hoping there's a standard way of handling it. First of all... I am defining a hook script for Subversion. To make things simple, I want to have a single file where the class (package) I'm using is in the same file as my actual script. Most of this package will have constants involved in it: print "This is my program"; package "MyClass"; use constant { FOO => "bar" }; sub new { yaddah, yaddah, yaddah. I would like my constant FOO to be accessible to my main program. I would like to do this without having to refer to it as MyClass::FOO. Normally, when the package is a separate file, I could do this in my main program: use MyClass qw(FOO); but, since my class and program are a single file, I can't do that. What would be the best way for my main program to be able to access my constants defined in my class? The second issue... I would like to use the constant values as hash keys: $myHash{FOO} = "bar"; The problem is that %myHash has the literal string FOO as the key and not the value of the constant. This causes problems when I do things like this: if (defined($myHash{FOO})) { print "Key " . FOO . " does exist!\n"; } I could force the context: if (defined("" . FOO . "")) { I could add parentheses: if (defined(FOO())) { Or, I could use a temporary variable: my $foo = FOO; if (defined($foo)) { None of these are really nice ways of handling this issue. So, what is the best way? Is there one way I'm missing? By the way, I don't want to use Readonly::Scalar because it is 1). slow, and 2). not part of the standard Perl package. I want to define my hook not to require additional Perl packages and to be as simple as possible to work.
